TUNING-PEG.

SPECIFICATION forming part of Letters Patent No. 778,128, dated December 20, 1904.

Application filed March 5, 1904. Serial No. 196,732.

To all whom it rim/7} concern.-

Be it known that I, FREDERICK O. GUTMAN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Tuning-Pegs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to tuning-pegs for violins or other stringed instruments.

It has for its object to provide a tuning-peg which will be simple of construction, cheap of manufacture, and which is adapted to be tightly clamped to prevent the strings from slipping.

The invention consists in the construction and combination of parts composing my in vention substantially as herein shown and described, and particularly pointed out in the claim.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a sectional view through an instrument-handle, showing my peg in place. Fig. 2 is a view of the peg detached, and Fig. 3 is a plan view of the Washer.

Referring more particularly to the drawings, my peg 1 is preferably made of metal in One piece and hasa shoulder 2, adapted to bear, as at 2", against the surface of the handle of the instrument. The stem 3 is straight and does not taper. Said stem is provided with a screw-thread for the nut 4: and flat surfaces 5 on opposite sides thereof for the washer 6, which has the opposite sides of its opening flattened, as at 7. The stem may be reduced, as at 8, beyond the screw-threaded surface and provided with an opening 9 for the string. It is obvious that when the peg is adjusted the washer will turn with the stem, preventing the nut from becoming loose, and the shoulder 2, bearing upon the surface of the handle of the instrument, will cause sufficient friction to prevent the slipping of the string. As the entire peg is made in one piece, the shoulder cannot slip with relation to the stem, so that once the peg is adjusted it will stay at the position it is given indefinitely without danger of different parts working apart.

The device is extremely cheap of manufacture, costing only about two cents apiece wholesale.

It will be noted that the shape of head of the peg and its shoulder may be varied at will and other changes made without departing from the spirit or sacrificing the advantages of my invention. I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

I am aware that pegs have been made with a shoulder of a separate piece from the stem. As suggested above, the disadvantage of this construction is that the parts work loose, allowing the peg and string to slip. By making a peg substantially all in one piece I overcome this vital objection.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A tuning-peg for stringed instruments in one piece, comprising a flange adapted to engage the surface of the handle of the instrument and a stem portion, adapted to pass through an aperture in said handle, having a screw-threaded portion of one diameter but its extremity of smaller diameter, said screwthreaded portion having its opposite sides flattened so that the distance between said surface is equal to the lesser diameter portion but leaving threads between said flattened surfaces whereby a washer may be slipped on to engage said fiattened surfaces, and a nut screwed on within the limits of said surfaces to adjust the peg to the handle of the instrument.

In testimony whereof I aiiix my signature in presence of two witnesses.

FREDERICK O. GUTMAN.
